Pulmonary Arteriovenous Malformations (PAVMs) are caused by abnormal communications between pulmonary artery and pulmonary veins, which are mostly congenital in nature. Although these lesions are quite uncommon, but they are important part of the differential diagnosis of hypoxemia, central cyanosis, clubbing, haemoptysis and remains a diagnostic challenge. We describe a case of 23-year-old, female who presented with hypoxemia, cyanosis, pandigital clubbing and exertional dyspnoea along with symptoms of tuberculosis and was diagnosed as complex PAVM on bubble ECHO and CTPA. Patient also fulfilled the criteria of possible HHT, according to Curacao Criteria. Later patient underwent percutaneous endovascular therapy with good clinical outcome. PAVM should be suspected in patients with unexplained central cyanosis and clubbing without any cardiac cause as they carry high mortality risk. Treatment is strongly recommended to prevent mortality and complications related to PAVMs.
